Causes and Repair of Fuel Injector Sticking
Fuel injectors are an essential component in an automobiles fueling system, and can sometimes get stuck. Sticking of Fuel Injector occurs when the fuel injector is partially open, allowing a small amount of fuel to continually spray into the engine intake manifold. This will allow fuel to continuously accumulate and create problems with engine performance which include stalling and poor acceleration. In this article we shall cover the causes and suggested repair methods of this problem.
Causes of Fuel Injector Sticking
1. Clogged Filter: In order to maintain optimal engine performance, the fuel injector needs a steady, unobstructed stream of clean fuel. A dirty fuel filter will impede the flow of fuel to the injector, and can cause it to get stuck.
2. Gelling: In cold weather, the diesel fuel can become thick and sticky. This gelled fuel can block the fuel injector opening and cause it to get stuck, preventing operation of the engine.
3. Debris: Debris from the fuel tank, such as rust and dirt, can also clog the fuel injector and lead to sticking.
Suggested Repair Methods for Fuel Injector Sticking
1. Flush fuel system: The fuel system should be flushed with a fuel additive in order to remove any debris or gelled fuel.
2. Replace Fuel Filter: A dirty fuel filter can impede the flow of fuel to the injector, and can cause it to get stuck. Replacing the fuel filter will help to remedy this problem.
3. Clean Fuel Injector: If the fuel injector is clogged, it should be cleaned with an injector cleaner. This will help to ensure a clean fuel supply to the injector.
4. Adjust injector pressure: If the injector is still sticking, the fuel pressure should be adjusted to ensure that it is set to the correct PSI for the injector.
5. Replace Injector: If all of the above steps fail, then the fuel injector should be replaced.
Conclusion
Fuel injector sticking can cause engine performance issues, such as stalling and poor acceleration. The causes of this problem include clogged filters, gelling fuel, and debris in the fuel tank. It is suggested that the fuel system be flushed, the fuel filter replaced, and the fuel injector cleaned to remedy this issue. If this does not resolve the problem, then the fuel pressure should be adjusted and the fuel injector should be replaced. This article has discussed the causes and suggested repair methods of fuel injector sticking.
